250 µCi quantities of [5,6-³H]-Uridine 5'-Triphosphate, Tetrasodium Salt are available for your research. Application of [³H]Uridine can be found in: effects of oocyte quality on development and transcriptional activity in early bovine embryos in livestock sciences, transcription factor expression, RNA synthesis, NADPH-diaphorase and exposure to spatial novelty in behavioral (rat) brain research, potential of various drugs to inhibit nucleoside uptake in rat cell line, cytidine as a novel substrate for wild-type concentrative nucleoside transporter 2 in environmental biochemistry, etc.

Special Information: CONVERSION TO OTHER SALTS: The tetrasodium salt may be converted to that of another cation by passing it through a small column of exchange resin in the form of the desired cation. A 1-2mL quantity of thoroughly washed resin is generally satisfactory. Necessary precautions should be exercised to minimize any breakdown from occurring during this procedure.

Removal of Solvent: An aliquot or the entire sample can be taken to dryness by directing a gentle stream of inert gas (nitrogen) over the surface of the solution. The temperature of the solution should not be allowed to exceed 20°C during the drying process, and the compound should not be permitted to remain in the solid state any longer than necessary.
